上游矿产企业盈利弹性显著释放，以章源钨业为例，每吨钨精矿成本约7万元，当前价格13.8万元/吨，毛利率从45%飙升至68%，净利润对钨价敏感系数达1.8（价格涨10%，净利增18%）。资源储量价值需重新计算，每万吨钨储量对应市值从50亿升至80亿。

In most disciplines, the next step is sending your paper to a peer-reviewed journal, where it gets evaluated by an editor and (if the editor sees some promise in it) a few reviewers. These people are academics just like you, and they generally do not get paid for their time. Editors maybe get a small stipend and a bit of professional cred, while reviewers get nothing but the warm fuzzies of doing “service to the field”, or the cold thrill of tanking other people’s papers.

The aarch64 instruction set has a madd instruction that performs integer multiply-adds. Cortex A725 and older Arm cores had dedicated integer multi-cycle pipes that could handle madd along with other complex integer instructions. Cortex X925 instead breaks madd into two micro-ops, and handles it with any of its four multiply-capable integer pipes. Likely, Arm wanted to increase throughput for that instruction without the cost of implementing three register file read ports for each multiply-capable pipe. Curiously, Arm’s optimization guide refers to the fourth scheduler’s pipes as “single/multi-cycle” pipes. “Multi-cycle” is now a misnomer though, because the core’s “single-cycle” integer pipes can handle multiplies, which have two cycle latency. On Cortex X925, “multi-cycle” pipes distinguish themselves by handling special operations and being able to access FP/vector related registers.
